Went to go play FS as i normally do.  But now I have problems that you only get with lag, but my game is fine and parts of it run fine(but a little jumpy). I get the same ping as I normally do. The main things are I hit the jump button and he starts to jump then snaps to the ground, or I go to get out of prone position and he snaps back down.  Other things have seemed weird but other parts seem fine.  I turned off my Firewall and that didn't do anything, I can't think of what might be doing it. It does something similar in BF2 were everything seems jump. It's not as bad but they may be connected. It is more noticeable in FS. A lot more. So if anyone has and ideas please tell me.
